Add ECM behavior to not Air to Air flights (#1879)

* If a plane has a jammer, and it is not an air to air flight it will jam between join and split.

changelog.md

@@ -9,6 +9,7 @@ Saves from 5.x are not compatible with 6.0.
 * **[Mission Generation]** Added an option to fast-forward mission generation until the point of first contact (WIP).
 * **[Mission Generation]** Add Option to enforce the Easy Communication setting for the mission
 * **[Flight Planning]** Added the ability to plan tankers for recovery on package flights.  AI does not plan.
+* **[Flight Planning]** Air to Ground flights now have ECM enabled on lock at the join point, and SEAD/DEAD also have ECM enabled on detection and lock at ingress.
 * **[Modding]** Add F-104 mod support
 * **[UI]** Added options to the loadout editor for setting properties such as HMD choice.
